To all whom it may concern Be it known that I, AUGUSTA P. MCKAY, acitizen of the United States, residing at Rome, in the county of Floydand State of Georgia, have invented certain new and iiseful Improvementsin Disk Flows; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. .1

My present invention relates to improvements in diskplows andsubsoilers, and it is intended to provide a framework and operativeparts made of steel, iron, or other suitable metal, in which the widthof the furrows may be varied within limits at Will, and in which thedisks and subsoil blades are so arranged, relative to the draft beam,that the tendency of the one to tilt the beam lat erally in onedirection is counterbalanced by the tendency of the other to tilt thebeam in the opposite direction.

My invention is also intended toprovide an arrangement of the characterdescrlbed, which shall be simple in construction and able to stand therough usage and exposure to weather to which such implements areordinarily subjected.

My invention also includes other novel features, and other novelarrangements and combination of parts, which will be more clearlyunderstood afterreference to the accompanying drawings, in which Figure1 is a plan view of the complete implement, omitting the seat and ltsattachment for the sake of clearness in the drawings; Fig. 2 showsasectionthrough Fig. 1, along the line 2-2 of said figure, and looking inthe direction of the arrows, the seat being shown in position; Fig. 3 isa rear View of the end of one of the draft beams, with the diskattachment and the subsoiler attachment connected thereto; Fig. 4 is ashowing a detachable block, adapted to be adjustably attached to themain ;casting to permit the lateral adjustment of the draft beamconnected thereto; Fig, 6 is'a perspec-' tive view showing details ofthe shifting lever and its locking sector; Figs. 7 and 8 are.

perspective views showing the casting to which the disks are journaled;andFig. 9 is a perspect ve view showing the arrangement for ad ustingthe position of the draft rods.

A represents the main casting (shown in detail in Fig. 4:), which isadapted to slide laterally on the main frame, and comprises twocylindrical sleeves a, one at each side, which sleeves are preferablyflanged at each end, as at a, and are connected together by the integralbed-plate a and the head A which projects upwardly to form the fixedblock A, which is perforated as at a to receive bolts for attaching saidblock to the outer draft beam, as will be hereinafter de- I scribedformed between the side sleeves a and the bed-plate a and this block Bis perforated to receive the clamping bolt 0. and also is perforated, asat 6 to receive bolts attaching the same tothe draft beam D.

In the drawings I have shown two draft beams, the one, D, securelyattached to the block A projecting upward from the end of the maincasting, and the other draft beam D secured to the movable block B whichis adjustably mounted on the main casting by means of the clamping boltC and nut a, which clamping bolt passes through the elongated slot a inthe main casting A. These draft beams D and D are of substantiallysimilar construction, except that the inner draft beam is longer thanthe outer, so as to stagger thedisk and subsoiler attachments. Thesedraft beams are preferably made of. trussed construction, in whichparallel bars are used, spaced apart by thimbles d and secured togetherby bolts passing through said thimbles. The rear end of each draft beamis bent toproject downward, as shown in Fig. 2, and to thisv downwardlyprojecting portion the castings or journal bearing blocks E, for thedisks F and F, are attached; and at the'lower end of the heel of eachdraft beam the housing block or casting for the shank H of the subsoileris secured.

The construction of the journal bearing blocks E for the disks F and Fis shown in detail in Figs. 7 and 8. These blocks E are set off to theleft of the draft beam,while the subsoiler housings G and G are set offto the right of the draft beam, as shown most clearly in Figs. 1 and 2,so that any lateral pressure on the disks, tending to twist the beamlaterally, will be compensated for by the counterbalancing pressure onthe subsoilers. This arrangement causes the subsoiler point to rundirectly in the bottom of the disk furrow, and also balances thetwisting effect of the plow disk and the subsoiler as described. Theblocks E are secured to the left side of the res )ective draft beams bymeans of the bolts 0 passing through the bolt holes 6, and the disk isjournaled in the bearing E and its journal is secured therein in theusual way.

The two subsoiler housings G and G are substantially similar, exceptthat the hous ing G is provided with a journal bearing 9 for thegoosencck I of the trail wheel, see Fig. 2, and with a tail lug 9adapted to engage the stop 2' carried by the rearwardlyprojecting curvedbar or gooseneck I, to which the wheel J is journaled in the usual way.This stop permits the trail wheel to swing to the left and to follow thefurrow cut, and also permits it to swing to the left in turning theimplement.

The housing blocks G and G are preferably curved, as shown in Figs. 1, 2and 3,

and provided with a reinforcing web he front ends of these blocks slipbetween the ends of the side bars constituting the draft beams, and areheld in place by means of the bolts (Z By this construction an eX-tremely strong and rigid connection between the housing blocks for thesubsoilers and the lower ends of the draft beams is secured. Thesehousing blocks G and G are provided with rectangular slots Gtherethrough for the shanks of the subsoilers, which shanks are held inplace by set screws h.

The depth to which the subsoilers are to cut is readily aejusted byeasing up on the clamp screws lb, moving the shanks to the desiredposition and clamping the same. These slots G in the housing blocks Gand G are preferably set at a slight angle to the perpendicular, so asto throw the foot of the subsoiler outward as shown in Fig. 3. Thisincreases the leverage at which the subsoiler acts to counterbalance thetwisting effect of the disk which acts in the op posite direction, aswill be evident from examining Fig. 3.

The seat X is attached to one of the draft beams in the usual or anyconvenient way.

' The main casting A slides on the main frame, which is composed of thetwo transverse bars M and M connected together at opposite ends by thesector plates N and N carrying the sectors N and N respectively. Thesesector plates and sectors with the bars M and M form a rigid frame, inwhich the stub axles O of the wheels P are journaled. Pivoted as at q onthese axles O are the levers Q carrying the housing Q, in which thespring pawls Q are mounted, which spring pawls are connected by the rodsQ3 to the handles 9 These housings Q are connected by links Q to thestub axles near the hubs of the wheels, as shown in Figs. 1 and 2, andby withdrawing the pawl q, and raising or lowering on the lever Q,either end of the main frame may be raised or lowered relative to thehub of its wheel, as desired; and thus the main frame may be keptparallel with the ground while the furrow wheels P and J are running intheir respective furrows.

In order to shift the main casting A laterally on the main frame, Iprovide a sector R secured to the cross bar M by means of the U-boltsand nut, and projecting forward beneath the front cross bar M. livotedto the forward portion of this sector R is the shifting lever S, whichis connected to the main casting A by means of the link T. It will beobvious that swinging this lever S to the right, or to the left, willmove the casting A along the cross bars M and M, thus varying the widthof the first furrow as desired. The width of the second furrow is variedby easing up on the clamp bolt C, moving the beam D to the right orleft, as desired, and then setting up on the nut c on the clamp bolt C,clamping the beam D in the proper position.

The shifting lever S is provided with a 7 suitable spring pawl 8 adaptedto engage the teeth R of the sector R, which sector is preferablyprovided with end lugs 1" to prevent the pawl from being thrown entirelyoff of the sector, see Fig. 6. This spring pawl is operated by the rod 3and handle 8 as shown in Fig. 1.

The forward end of the beam D is provided with a curved bar D heldbetween the side plates as shown in Fig. 1. This bar is curved, as at (Zto give the desired resiliency when the two beams are spread apart, andextends transversely across the front of the implement, as shown at (Zin Fig. 1. Connected to this portion (Z of the bar D is the L-shaped barD which is secured between the side bars of the draft beam D. Theportion (Z of the bar D is provided with a series of perforations (Z asshown in Fig. 9, through which pass the bolts is and 70 for adjustablysupporting the metal straps K and K, which are perforated at the lowerends, as at 70, to permit the passage therethrough of the draw-bar L,

Whose lower rear end is secured to the main casting A, and whose forwardend is provided with a hook L, or any other suitable device, forconnecting the same to the source of motive power, such as a team ofanimals, a tractor engine, a pull-rope, or the like. By this arrangementthe forward end of the draw-bar may be raised or lowered, or moved tothe right or left, so as to adjust the hook L to the proper position forhooking on to the team, or other source of motive power, and to get theline of pull on this draw-bar in the proper direction.

The operation of the device is as follows :--The width of the furrowbeing predetermined, set the draft bar D at the proper distance from thebar D, which may be done by means of the clamp bolt 0 and nut c, andthen by means of the shifting lever S move the main casting so that thebar D shall be at the proper distancefrom its end of the main frame,which will determine the width of the first furrow; the distance betweenthe two bars D and D determining the width of the second furrow. Thenrelease the spring pawl s, hook on the implement to the team, or tractorengine, and the parts are ready for the operation of plowing. Either endof the frame may be raised or lowered by means of the hand levers Q, soas to set the main frame in the proper position relative to the surfaceof the ground.

WVhile I have shown two draft beams D and D, with the implementsattached thereto, it will be obvious that, by simply length ening themain casting A, one or more addi-' tional beams may be mounted on saidcasting, in which event, of course, the main frame would have to belengthened trans: versely to permit the increased length of the maincasting A. It will be seen that the sec tor B may be moved to anydesired position on the cross bar I by simply easing up on the nuts ofthe U-bolts r, sliding the sector to the desired position and clampingthe U-bolts in place again. In this way the length of vibratory movementof the main casting A on the main frame may be varied beyond the limitspossible where the sector, on which the shifting lever is mounted, is

secured at a given point only on the main frame.

It will be obvious that various modifications might be made in theherein described apparatus, and in the construction, combination andarrangement of parts which could be used without departing from thespirit of my invention.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is 1. In an agricultural implement,of the character described, the combination with a main frame providedwith cross bars, of
